BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a tool storage bag and a tool storage bag set, where the tool storage bag includes an inner tray disposed inside the bag, the inner tray being in the shape of a box with a bottom and an open top to store power tools.

2. Description of the Related Art

Japanese Patent Application Publication No. 2009-248262 discloses a tool storage box that stores a hand-held power tool with a grip extending from a side of the main tool body so as to accommodate the power tool with a forward leaning posture holding the forward end of the main tool body and the rear end of the grip. According to the tool storage box of the above-mentioned Publication, the hand-held power tool can be stored in the tool storage box with a forward leaning posture which is almost the same posture as when it is in use. Thus, it is not necessary for a user to shift the hand-held power tool from one hand to the other to change his working posture when storing the power tool in the tool storage box. Further, the user is able to start using the hand-held power tool with the same posture as that when the power tool is taken out from the tool storage box.

SUMMARY OF THE INVENTION

The above-described tool storage box includes a mount, made of a hard resin or other like materials, that is formed to match the shape of a power tool, such as the hand-held power tool, to maintain the forward leaning posture of the power tool. Various shaped mounts are required to form mounts to fit various shapes of a power tool respectively, which increases manufacturing costs for the tool storage box.

In addition, the mount is integrally provided in the tool storage box. Therefore, it cannot be detached from the tool storage box. As a result, different tool storage boxes need to be prepared for different power tools, which reduces the versatility of the tool storage box.

The present invention has been made in view of the above circumstances, which provides a tool storage bag and a tool storage bag set having excellent versatility and reducing manufacturing costs.

A tool storage bag according to a first aspect of the present invention includes an inner tray that is disposed inside the tool storage bag and is in the shape of a box with a bottom and an open top to store power tools. The inner tray is made of fabric members. The inner tray is detachably disposed inside the tool storage bag where an outer surface of the inner tray is supported by an inner surface of the tool storage bag, or is detachably disposed with a positioning unit provided between the inner surface of the tool storage bag and the outer surface of the inner tray.

According to a second aspect of the invention, the inner tray has handles on the side faces in the first aspect.

According to a third aspect of the invention, oil resistant coating is applied to at least an inner bottom surface of the inner tray in the first and second aspects.

According to a forth aspect of the invention of the first and second aspects, the inner tray includes one pair of opposed side faces with core members, and the other pair of opposed side faces connected to the one pair of side faces and not having core members, and the inner tray is collapsed by folding the other pair of side faces toward the inside of the inner tray to cause the one pair of side faces to overlie the other pair of side faces.

A tool storage bag set according of the invention includes plural tool storage bags made of different materials in the above-mentioned embodiment, and the inner tray can be mutually used among the tool storage bags in the first and second aspects.

According to the tool storage bag of the first aspect of the invention, as the inner tray disposed in the tool storage bag is made of a fabric material, a mold to manufacture the inner tray is not necessary. As a result, costs for manufacturing the tool storage bag can be reduced.

In addition, as the inner tray can be fixed inside the tool storage bag in an attachable and detachable manner so that the inner tray can be detached from the tool storage bag, a single inner tray can be disposed in plural different tool storage bags. Therefore, the versatility of the tool storage bag is increased.

Further, a user can easily put the inner tray into the tool storage bag and take it out from the tool storage bag while holding the handles.

Furthermore, according to the second aspect of the invention, even if lubricant oil or the like used in the power tool stored in the inner tray leaks, the oil-proof coating applied on the inner bottom surface of the inner tray can prevent the oil from spreading to the interior of the tool storage bag.

Moreover, according to the third aspect of the invention, when the other pair of opposed faces are folded toward the inside of the inner tray, the one pair of opposed faces connected with the other pair of faces can overlie the inwardly collapsed other pair of opposed faces. Thus, the inner tray can be compactly folded up for transportation.

Further, according to the fifth aspect of the invention, the tool storage bags do not require their own dedicated inner trays, thereby increasing the versatility of the tool storage bags.

In addition, the user can choose an appropriately sized inner tray for the power tool and dispose the inner tray into any one of the plural tool storage bags. In other words, the user can freely select and use an appropriate tool storage bag from the plural tool storage bags depending on intended use.

DETAILED DESCRIPTION OF THE INVENTION First Embodiment

A first embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG. 1 shows a first inner tray 1 that is made of fabric pieces (fabric members) and is to be disposed inside a tool storage bag 20 which will be described later. The first inner tray 1 includes a tray body 2 and a partition unit 5.

The tray body 2, as shown in FIG. 1A, is in the shape of a box with a substantially square bottom and an open top and is formed by the fabric pieces sewed together. As shown in FIG. 1B, a thin strip-shaped hook-and-loop fastener T1 is affixed on an outer bottom surface 2A of the tray body 2. The tray body 2 includes a pair of side faces 3A, 3B and arc-shaped handles 4, 4 sewed so as to extend upward from the upper ends of the side faces 3A, 3B.

The partition unit 5 includes a fabric partition 5A placed in parallel with the lateral direction of the tray body 2 and a fabric partition 5B substantially-orthogonally sewed to the fabric partition 5A, the fabric partitions 5A and 5B forming a substantially T shape. The partition unit 5 divides the interior of the tray body 2 into three compartments 6A to 6C. The compartments 6A and 6B can be used to store battery packs, while the compartment 6C can be used to store a charger, for example.

FIG. 2 shows a second inner tray 10 formed by sewing fabric pieces so as to have a box shape with a substantially square bottom and an open top. The second inner tray 10 has a height less than the height of the first inner tray 1, and inner surfaces 11 of the second inner tray 10 covered with an oil resistant layer. The oil resistant layer is typically formed by enamel coating which is applied on the inner bottom surface and inner side surfaces. As shown in FIG. 2B, two thin strip-shaped hook-and-loop fasteners T2, T2 are affixed at an interval on an outer bottom surface 12 of the second inner tray 10. In this embodiment, the second inner tray 10 stores a main body of a chain saw. It should be noted that the chain saw is an example of a power tool in the present invention.

A tool storage bag 20 for storing power tools therein in FIGS. 3 and 4 is a soft case bag made of fabric materials. The tool storage bag 20 includes a bag body 21 and a cover 22.

The bag body 21 is shaped into a substantially rectangular box and has a slide fastener (not shown) on the upper edges of three faces, except for the back face, of the bag body 21 so that the top face of the bag body 21 serves as a cover 22 openable and closable with the slide fastener. As shown in FIG. 3B, thin strip-shaped hook-and-loop fasteners T3, T4 are affixed to the inner bottom surface 23 of the bag body 21.

Referring to FIG. 4, a procedure for disposing the first and second inner trays 1, 10 in the bag body 21 is explained. Firstly, the first inner tray 1 is disposed inside the bag body 21. For example, a user guides the first inner tray 1 from the top opening of the bag body 21 into the interior of the bag body 21, while holding the handles 4, 4, and presses the tray so as to attach the hook-and-loop fastener T1 of the tray body 2 to the hook-and-loop fastener T3 of the bag body 21. As the hook-and-loop fasteners T1 and T3 are attached each other, the outer bottom surface 2A of the tray body 2 and the inner bottom surface 23 of the bag body 21 are securely coupled. Secondly, the second inner tray 10 is disposed in the bag body 21. The hook-and-loop fasteners T2, T2 and hook-and-loop fasteners T4, T4 are pressed together so that the outer bottom surface 12 of the second inner tray 10 is securely coupled to the inner bottom surface 23 of the bag body 21.

On the other hand, when the first and second inner trays 1, 10 are taken out from the bag body 21, the user unhooks the hook-and-loop fastener T1 of the tray body 2 from the hook-and-loop fastener T3, while holding the handles 4, 4, to detach the outer bottom surface 2A of the tray body 2 away from the inner bottom surface 23 of the bag body 21. The user then holds the side faces or any other portions of the second inner tray 10 by hand and unhooks the hook-and-loop fasteners T2, T2 from the hook-and-loop fasteners T4, T4 to detach the outer bottom surface 12 of the second inner tray 10 away from the inner bottom surface 23 of the bag body 21.

In the above-described manner, the first and second inner trays 1, 10 can be attached to and detached from the interior of the tool storage bag 20. It should be noted that the inner bottom surface 23 of the bag body 21 merely shows an example of an inner surface of the tool storage bag of the present invention, and the outer bottom surface 2A of the tray body 2 and the outer bottom surface 12 of the second inner tray 10 are just an example of an outer surface of the inner tray of the present invention. Further, each of the hook-and-loop fasteners T1 to T4 merely shows an example of a positioning unit of the present invention.

As shown in FIG. 5, the first inner tray 1 is collapsible. The first inner tray 1 is formed of a base material 8, such as cardboard, covered with fabric pieces. A pair of opposed side faces 3A, 3B made of fabric pieces includes core members (not shown) made of cardboard. On the contrary, the other pair of opposed side faces 3C, 3D made of fabric pieces does not include core members. The pair of side faces 3A, 3B and the other pair of side faces 3C, 3D are continuously connected to one another.

In order to fold the first inner tray 1, the other pair of side faces 3C, 3D, which does not include the core members, is folded to the inside of the first inner tray 1 as shown in FIGS. 5A, 5B, resulting in the inwardly collapsed side faces 3C, 3D. The movement of the side faces 3C, 3D pulls the pair of side faces 3A, 3B connecting to the side faces 3C, 3D inward, and the side faces 3A, 3B lie on top of the collapsed side faces 3C, 3D while pushing down the fabric partitions 5A, 5B from above. In this way, the first inner tray 1 is completely folded.

Effect of First Embodiment

According to the tool storage bag 20 in the first embodiment, the first and second inner trays 1, 10 are formed by the fabric pieces sewed together. Therefore, molds for manufacturing the inner trays 1, 10 are not necessary, which leads to reducing the cost for manufacturing the tool storage bag 20 with the inner trays 1, 10 disposed therein. Additionally, the use of the hook-and-loop fasteners T1 to T4 to affix the outer bottom surface 2A of the tray body 2 (first inner tray 1) and the outer bottom surface 12 of the second inner tray 10 to the inner bottom surface 23 of the tool storage bag 20 allows to be attachable to and detachable from each other so that the inner trays 1, 10 can be taken out from the inner bottom surface 23. Accordingly, the inner trays 1, 10 can be disposed in plural and different tool storage bags, thereby providing a highly versatile tool storage bag 20.

The handles 4, 4 can be used to guide the first inner tray 1 to the inner bottom surface 23 of the tool storage bag 20 and to pull it away from the inner bottom surface 23. Thus, it is easy to facilitate placement of the first inner tray 1 into and out of the tool storage bag 20.

Further, even if lubricating oil or the like used in a chain saw leaks from the main body of the chain saw stored in the second inner tray 10, the oil resistant layer applied on at least the inner bottom surface of the tray prevents the oil from spreading from the second inner tray 10 to the interior of the tool storage bag 20.

Furthermore, folding of the other pair of the opposed side faces 3C, 3D inward the first inner tray 1 causes the pair of side faces 3A, 3B connected with the side faces 3C, 3D to overlie the inwardly collapsed side faces 3C, 3D. Therefore, the first inner tray 1 can be folded, making it compact and easy to carry.

Second Embodiment
